i've just rechecked this and the problem simply was that
libpcc.a was not compiled with -fPIC
(it used to work because i didn't specify -lpcc when building libc.so
and later i only tried dynamic linking with pcc
which adds -lpcc automatically so there were no missing symbols)
but i guess it would be nice if musl implemented long long arithmetics
and made -lpcc/-lgcc unnecessary
(i'm not sure where alloca should go, pcc does not provide it)
